Hey, what’s going on, I’m Mercy of DiscountLowVoltage.com and I’m going to show you guys how to make a telephone cable. Now before we get started on crimping, the plugs, testing, cutting, that sort of thing, the most important thing about this cable is you need to know the USOC pinout. Oh, there it is. So this USOC pinout, depending on if you need a one-pair, a two-pair, a three-pair, or four-pair, this pinout is what you want to stick to when you’re making your cable. Now let’s get to it. Okay, so I have some snaps, a tester, a crimp tool, some mod plugs, a RJ11 six-conductor, and an RJ45 plug. We have blue Cat5e cable, and Cat3 cable in white, of course. If you’re using Cat5 for telephone, no problem, no sweat, as long as you’re still using that USOC pinout we talked about earlier.
Okay, so let’s go ahead and start. Let’s cut off a piece of this cable off. There we go. Now you’ll see this pull string here, let’s get rid of that, get out of the way. OK. Now as you can tell, you have an orange pair, you got your blue pair, brown pair, and green pair, depending on what you’re doing, just follow the color-code USOC guide and boom! Now the plug we’re going to do is a six-conductor RJ11 mod plug. So being that that’s a three-pair plug, we’re going to line up the color code to what we need it to be at. Alright, now that we got our pairs straightened out to the color code, we’re going to get rid of this pair. We don’t need this, so go ahead and snip that off here at the bottom. There we go. Now the next step is to, we want to keep these wires as straight as possible when we put it in the plug, but we probably only need, I don’t know, maybe a quarter inch of this, so let’s go ahead and trim this down. There we go.
Now I always like to push a little bit of pressure on my onto these conductors, because it helps to keep them straight. That way they don’t wobble around everywhere. Now let’s get out our mod plug. Now as you can tell, the plug itself, it has this little kind of slot here where the crimp tool is going to come down on it and secure onto the jacket, and the little mod plugs, the gold pins here, they got some teeth. Now they get crimped into the copper conductor inside the plug. Now let’s try to slide this plug on. Now as you’re putting it in, I press up. I press up into the mod plug. It helps keep the wires straight, and then I slide it in there. You kind of get a feel for it. Sometimes it won’t go straight in, so you have to kind of feel it out, move it around a little bit. Make sure it’s in there. And then you want to push the jacket in. There we go, you want to make the jacket get in there too.
Actually, it helps to have it in there as much as possible so this back slot gets crimped down onto it. Another thing you might want to do is you might want to take a look at the conductors in there. It’s hard to tell, but double check that to see if they line up correctly with the USOC pinout and if they do, then we want to go ahead and crimp it. If they don’t, you’re gonna have to pull this out, make sure they’re straight, put it back in there before you crimp it. Now another thing you might want to do, it’s hard to tell, but in the very front of this plug, you can kind of see the conductors pressed up to the mod plug. I always like to press in the cable also, because that helps the copper conductors get terminated and make proper contact with those gold pins once they’re in there. Now let’s crimp this.
Now the tool we got here, it’s a crimp tool, but it has the for the eight-position, the six-position, the four-position cable. We want to put it in the appropriate slot. Let’s pop it in there, and then I always- once again, I like to push in a little bit while it’s in there. Now let’s give the squeeze. Now let’s do the RJ45. Here’s our Cat5 cable, let’s go ahead and cut a piece of this off. Now we’re just gonna do the same thing with the- this cable as we did with the Cat3 four-pair, but that was a, you know, a different connector, the RJ11. This is the RJ45, let’s get to it. There we go. So we got ’em sorta straightened out, you want to definitely double-check these color code at the bottom here, towards your thumbnail. Make sure you got the pinout straightened out, almost trim some of this off. There we go. I want to take a look at it and make sure the pairs are where they need to be.
Looks like we got an orange pair out of place, so we’re gonna go ahead and just kind of move the cable around a little bit. There we go. Keep it straight. Okay. There we go. Now we’re gonna do the same thing with the RJ45 plug like we did with the RJ11. You want to kinda push up into the plug. Push it all the way in. Make sure the front of the plug here is making contact. I mean, it doesn’t have to make perfect contact, but it’s nice to see the pairs all the way in there to where the gold pins can crimp down on them, and don’t forget, you also want your jacket in there past this little prong piece. So crimp tool crimps right into that, boom! Make it a nice, tight, and a proper fit, so that way this jacket doesn’t come out later when you’re pulling the cable out. Now let’s crimp it. Okay. Got our crimp tool with the eight-position slot. Go and slide your plug in there. I push in a little bit into the plug so that way, your plug is, you know, it’s just a little thing that makes me feel a little better. I squeeze it. Boom. There we go. As you can tell, I don’t know if you can tell or not, but the crimp tool, like I said, this little piece right here, it goes in there, squeeze in this little prong onto the jacket, and inside the tool end here, you’re actually getting the gold pins terminated into the conductors. Let’s see if I can get a good shot here for you. Yeah, see? That’s what I’m talking about. Okay, so the last step here, if you’re going to make a lot of these, you might want to buy a continuity tester. This one checks the 10-base T, 56B pinout, the USOC pinout, or the 568B. Now let’s plug the Cat3 patch cable I made into it. Okay. So this was a six-conductor three-pair cable. I have green lights. Let’s check the other side. Alright, we wired it properly.
Alright, so hopefully you learned something today and I helped save you guys some dough for you do-it-yourselfers, and that’s basically it. You can do a Cat3 or a Cat5 cable for telephone cables, but remember, the USOC pinout, that is a universal thing that all the Cat3 cable is wired to. Questions, call us. Number here’s 888-797-3697.
